Failure Pyramid * Pre-condition to Failure * Environmental factors * Design flaws * Incorrect installation * Hidden Failure * Degradation of components * Manufacturing defects * Component Failure * Failure of individual components * Functional Failure * Failure of the system to meet its requirements Pre-condition to Failure The bottom layer of the pyramid is the pre-condition to failure. This is the set of conditions that must be met in order for a failure to occur. These conditions can be environmental factors, design flaws, or incorrect installation. Pre-Condition to Failure is a condition that makes a functional failure more likely. For example, a software bug that is not detected and fixed could lead to a functional failure in the future. Another example, a pre-condition to failure for a software system might be that the system is not properly cooled. If the system is not properly cooled, it may ove...
Automotive infotainment is a system that provides entertainment and information to the driver and passengers of a vehicle. It typically includes a touchscreen display, a navigation system, a media player, and a variety of other features. The first automotive infotainment systems were relatively simple, with basic features such as AM/FM radio and cassette players. However, as technology has advanced, infotainment systems have become increasingly sophisticated. Modern infotainment systems can now include features such as: Touchscreen displays Navigation systems Media players Bluetooth connectivity Voice control Internet access Smartphone integration Advanced driver assistance systems (ADAS) Infotainment systems are becoming increasingly important in the automotive industry. They are seen as a way to differentiate vehicles from each other and to provide a more comfortable and enjoyable driving experience. There are a number of different automotive infotainment platforms available, inclu...
The three-level hierarchy of the driving task according to Donges (1982) is a model that describes the different cognitive demands of driving. The three levels are: Navigation level: This level is concerned with the planning of the route and the selection of the appropriate speed. It is the highest level of the hierarchy and requires the most cognitive effort. Command level: This level is concerned with the definition of a trajectory for the vehicle. It takes into account the current situation, such as the traffic conditions and the road layout, and generates a plan for how to reach the destination. Stabilization level: This level is concerned with the control of the vehicle to follow the desired trajectory. It is the lowest level of the hierarchy and requires the least cognitive effort. The three levels of the hierarchy are not always clearly separated. For example, the driver may need to make decisions about the route at the command level, or they may need to make...
